Thanks for the guidance, Austin and Phil.

Are you aware of software that can take a database of scores (I have a tennis database with about about 750,000 records) composed of player 1, player2, date, games for, games against (+ some other miscellaneous data) and produce a ranking? If so, what type of anaylsis would be appropriate?

If there is limited choice, are you aware of a suitable algorithm that I can use to create such software?

Many thanks to anyone who can assist.

I will be happy to share any new process with the list.

Jeff

I just skimmed Glickman's "A Comprehensive Guide to Chess Ratings," and that includes a very nice description of the Bradley-Terry model and how it relates to the Elo rating system.
